Abstract

PURPOSE: To obtain a small-size elastic surface wave resonator which is excellent in both the working efficiency and the mass-productivity, by forming the elastic surface wave resonator and the serial capacity into one body.
CONSTITUTION: The inter-digital electrode 4 formed on the substrate 3 is composed with a pair of comb-line electrodes 5 and 6 inserted alternately. The common part of one electrode 5 is extended to form the 1st conductive film 7 in the fixed form which functions as the capacitor electrode. The piezoelectric thin film 9 is formed on the substrate 3 including at least the electrode 4 and the film 7 and excluding the terminal part 8, and the 2nd conductive film 10 is formed on the film 9 to oppose to the film 7. A function can be secured for the film 10 as the capacitor electrode and the terminal part of the other side. Thus the film 9 is inserted between the films 7 and 10, and the film 9 produces the electrostatic capacity between the films 7 and 10 as the dielectric substance. This electrostatic capacity is connected in series to the resonator consisting of the electrode 4 and between the terminal parts 8 and 10.
